  3. Go in the Keychain Access menu in the upper left next to the Apple menu and choose Preferences
  4. In the General tab, check the box next to Show keychain status in menu bar
  5. A padlock will appear in the menu bar for your account on this computer from now on. Click on the padlock icon in the menu bar and choose Lock Screen.
